NetViz is a
visualization frontend for a "concept" oriented
search engine. NetViz features an interactive 3D
visualization of the relationships between concepts and
their associated documents.

NetViz is
currently being developed by Ben Houston and Zack
Jacobson. Considerable help has come from the comments
and suggestions of Justin Hollands, James Wise, Robert
Garigue, Milan Kutcha, Diane Keller, Els Goyette, Bill
Wright, Kristopher Lyon, Martin Taylor and Linda
Stilborne.
